Flex OLAP aggregating strings.

I recently got many queries about support for String aggregation in Flex OLAP. The current implementation available out of the box doesn't support this.

Here are the changes to source files required to support this. The files need to be unzipped into the fbpro directory and the datavisulization.swc needs to be build using the steps mentioned here.

The result would look something like this.

The sample project has a StringAggreator implementation which can be used as a starting point to build your own logic into the StringAggregator. The sample one appends the strings to each other.

Here is the sample project.

Of-course I might have missed something while testing. So let me know if you find any bugs !
